Patterns of primary afferent depolarization of segmental and ascending intraspinal collaterals of single joint afferents in the cat

Abstract

We have examined in the anesthetized cat the threshold changes produced by sensory and supraspinal stimuli on intraspinal collaterals of single afferents from the posterior articular nerve (PAN). Forty-eight fibers were tested in the L3 segment, in or close to Clarke’s column, and 70 fibers in the L6–L7 segments within the intermediate zone. Of these, 15… (More)
